The carrier member 3 is controlled to be movable until the center of the hole 55 of the carrier member 3 coincides with the optical axis of the irradiation unit 13, and in this state, the carrier member 3 is placed outside the back surface of the main body case K. An opening hole 5 is provided on the back side of the main body case K so that it can be projected. The distance that the carrier member 3 moves by one-step rotation of the second motor 41 is larger than the distance that the carrier base 12 moves by one-step rotation of the first motor 32. For this reason, at the time of preview, the carrier member 3 moves quickly, so that the reading speed of the image data is high, which makes it possible to quickly specify the reading target at the time of preview.

The transparent original 4 can be sandwiched between the front surface and the back surface by the base surface of the carrier member 3 and the plastic plate by being fitted between the transparent original 4 and the plastic member 3, and thus the transparent original 4 is prevented from bending. In this case, photographic film or the like is generally divided into 6 frames at the time of print service. Therefore, when the transparent document 4 for 6 frames is fitted into the carrier member 3, each frame of the transparent document 4 is individually scanned in the document window. 51, ..., 51 are located directly above. As a result, when light is emitted from the irradiation unit 13, the transmitted light reaches the reflection plate 23 via the transparent original 4 and the original window 51.

You can do it. As described above, as a result of covering the hole 57 with the tea base film, the density of the light transmitted through the tea base film is detected by the CCD 25, and the shading correction of the image and the black-and-white color reference adjustment can be performed based on the density. There is. In this case, since the transparent original 4 and the brown base film are sandwiched between the front and back sides by the plastic plate and the base surface, the transparent original 4 and the brown base film are effectively prevented from being bent, and the image data reading conditions are made the same. As a result, it is possible to accurately generate correction data at the time of shading correction and white reference adjustment. Also, the plastic plate and the window 54 (or 55)
The base surface that forms the edge of the CCD is the CCD inside the apparatus main body 2.
Since the brown base film is sandwiched along the main scanning direction of the image reading of 25 (the arrangement line direction of the CCD 25, that is, the direction shown by the arrow B in FIG. 5A), the deflection in the main scanning direction is generated. As a result of being prevented more effectively, the correction data can be generated with extremely high accuracy. further,

Is formed with a notch 58 for aligning with the image reading position. On the other hand, an interrupter is arranged in the main body case K (not shown), and if the interrupter detects the passage of the notch 58 together with the tip of the carrier member 3,
The main CPU 71 (see FIG. 14) outputs a drive signal for driving the motor to the second motor 41 based on the passage detection signal, so that the transparent original 4 can be aligned. ing.

As shown in FIG. 15, the above-mentioned irradiation unit 13 has a circuit 61 for lighting a lamp (hereinafter referred to as "inverter circuit 61") and a xenon lamp 62, 63, 64 which is a light source for image reading. And xenon lamps 62 and 6

Is equipped with. Since the lamp case 91 and the connector 93 are provided, the lamp case 91 can be easily removed and the xenon lamps 62, 63, 64 can be easily replaced. Also,
Inverter circuit 61 and xenon lamps 62, 63, 64
Since the wiring is placed on the substrate 90, the wiring by the electric wire can be omitted, and there is an effect of preventing the electric vehicle from being caught in the moving space of the carrier member 3 due to the slack of the electric wire. Further, by disposing the lamp case 91 on the same substrate as the inverter circuit 61, the assembling property and the maintainability are improved, and the space saving effect by reducing the wiring space and mechanical fixing means is reduced, and the image reading device 1 is miniaturized.

82 (see FIG. 14), the image data of the color image is 3
It is stored for each color.

Next, referring to FIG. 14, the image reading apparatus 1
The control system will be described.

The circuit block diagram shown in the figure shows a main circuit including the control circuit 70 of the image reading apparatus 1. Each electric circuit component is mounted on the above-mentioned printed board 16. The control circuit 70 is a main C that is the core of various processes.

In addition, the gate array 72 outputs the lighting control signal via the inverter circuit 61, and thereby the xenon lamp 62.
Lamp control section 81 for controlling the lighting of up to 64, a buffer RAM 82 for storing image data, and an A / D conversion section 73.
The image control unit 8 which takes in the image data output from the image processing unit, stores it in the buffer RAM 82 in association with each pixel, and performs shading correction, black-and-white color reference adjustment, and the like.
3 and a CCD control unit 84 for controlling photoelectric conversion of the CCD 25 by outputting a CCD control signal in accordance with a storage interval signal, a shift signal and a clock signal output from the main CPU 71.

Next, the image reading process in the image reading apparatus 1 will be described.

First, when the carrier member 3 is inserted into the carrier insertion port 11, the tip of the carrier member 3 passes through the interrupter, and the interrupter outputs a passage detection signal to the main CPU 71. The main CPU 71 outputs a drive signal and drives the second motor 41 to guide the carrier member 3 to a predetermined standby position in the main body case K. In this state, when a signal instructing preview is output from the image display device via the interface unit 74, the main CPU 71 outputs a drive signal to the second motor driver 76 to drive the second motor 41, The carrier member 3 is moved until the passage detection signal of the tip portion is output. At this time, the hole 54 is located directly below the xenon lamps 62-64. Then, the main CPU 71 outputs the CCD control signal without turning on the xenon lamps 62 to 64, thereby outputting the CCD 25.
The image control unit 83 is caused to read the image data from. Next, the main CPU 71 causes the image control unit 83 to set the image data at this time to a luminance level of 0 gradation, thereby performing black level adjustment. In this case, the brightness level of the image data is set to 256 gradations for each color, and 0 gradation corresponds to the black level and 256 gradations corresponds to the white level.

Next, the main CPU 71 turns on the xenon lamps 62 to 64 and causes the image controller 83 to read the image data from the CCD 25. The main CPU 71 controls the built-in R so that the maximum value of the image data read at this time has a gradation of about 230 to 250.
The second motor 41 according to the γ table stored in the OM
The white level adjustment is performed by adjusting the driving speed of the above, or adjusting the lighting time of each of the xenon lamps 62 to 64. At the same time, the main CPU 71 causes the image controller 83 to execute shading correction. That is, depending on the amount of light of the xenon lamps 62 to 64, the reflection coefficient of the reflection plate 23, the aberration of the condenser lens 24, etc., C
The correction data is generated so that the image data of one row of the CD 25 has 256 gradations. In this case, when the brown base film of the negative film is attached to the hole 54, the brightness transmitted through the tea base film is set to the white level, and when the brown base film is not attached, the hole 54 is opened. The correction data is automatically generated so that the brightness of the light that has passed directly becomes a white level. By these processes, the dynamic range of the brightness level of the image data can be automatically maximized. In the above-described series of operations, the black level adjustment, the white level adjustment, and the shading correction are performed by detecting the tip end portion by the hole 54, but these adjustments may be performed by the hole 55.

Next, the main CPU 71 outputs a drive signal, so that the end of the leading (first) document window 51 is positioned at the beginning of the reading position.
After moving, the image reading is started. At the time of reading an image, the lamp control unit 8 is switched from the main CPU 71.
By outputting various parameters to 1, the lamp control unit 81 outputs a lighting control signal to the inverter circuit 61, whereby the xenon lamps 62 to 64 are turned on. The main CPU 71 causes the image control unit 83 to read the image data of the image while outputting the drive signal and the CCD control signal.

The read image data is sent to the image controller 8
After the shading correction, the color correction, and the enlargement / reduction processing are performed by 3, the data is temporarily stored in the buffer RAM 82. Then, the main CPU 71 has a buffer RAM 82.
The image data stored in is read and output to the interface unit 74. At the same time, the interface unit 74
Converts the image data into data of a predetermined communication format and outputs the converted data to the image display device.

After reading the image of the transparent original 4 corresponding to the first original window, the main CPU 71 continuously outputs the drive signal and rotates the second motor 41 a predetermined number of steps to make the second original. The carrier member 3 is moved so that the end of the window 51 is located at the beginning of the reading position. Then
The main CPU 71 causes the image control unit 83 to read the image data of the transparent original 4 by outputting various parameters to the lamp control unit 81 and the image control unit 83. The main CPU 71 repeats these processes to sequentially output the third to sixth document windows 51,
, 51, the image data of the transparent original 4 is read, and the image data is output to the interface section 74 each time. Note that in this preview processing, CC
At D25, the outputs of a plurality of adjacent CCD elements are combined into one pixel data, so that the reading is performed at a resolution of about 50 to 300 dpi, which is lower than the resolution at the time of reading the main image. Thereby, the reading time of the preview can be shortened. Further, since the image reading accuracy may be somewhat low, some play between the carrier base 12 and the carrier member 3 is allowed, and for example, the opening area of the carrier insertion port 11 may be widened, By loosening the engagement between the rack 46 and the sixth gear 45, the carrier member 3 can be easily inserted into the main body case K.

The image display device stores the input image data in the image data RAM (not shown), and when a predetermined key operation is performed, the image of the transparent original 4 in the designated original window 51 is displayed on the display device. To do.

On the other hand, when the user confirms the image on the display device and then designates a frame by key operation,
A frame designation signal is output from the image display device to the main CPU 71 via the interface unit 74. Main CP
The U 71 drives the second motor 41 by a predetermined number of steps by outputting a drive signal to the second motor driver 76, so that the document window 51 of the designated frame is located at the beginning of the reading position. To guide you. Next, the main CPU 71 starts the main image reading, and the first
By outputting a drive signal to the motor driver 75, the first motor 32 is driven by a predetermined number of steps so that the carrier table 12 moves by one frame of the document window 51. At the same time, the main CPU 71 outputs a lighting control signal and a CCD control signal,
The above-described shading processing and black-and-white color reference adjustment are executed, and the image data is read. In this case, the carrier base 12 in one step rotation of the first motor 32
Since the moving distance of is extremely small, the image can be read with high accuracy. The read image data is output to the image display device by the main CPU 71 through the interface unit 74 in the same manner as described above. After that, in the image display device, an image display process based on the image data, an image processing / correction process such as brightness adjustment of the image data, an embedding process for fitting an image of an arbitrary frame into an image of another frame, and an MO (optical Magnetic disk) and D
Writing processing to a storage medium such as AT, MD, and floppy disk is performed.

As described above, according to the image reading apparatus 1 of the present embodiment, it is necessary to put the whole carrier member 3 from the front end to the rear end into which the transparent original 4 composed of a plurality of frames can be mounted in the main body case K. Since it does not exist, the size of the main body can be reduced.

According to the irradiation unit 13 of this embodiment, the xenon lamp is provided with the lamp case 91 accommodating the xenon lamps 62, 63, 64 and the connector 93 for connecting the lamp case 91 and the substrate 90. Replacing the lamps 62, 63, 64 becomes easier. In addition, the inverter circuit 61 and the xenon lamps 62, 63, 64 are mounted on the substrate 9
Placing the device on the surface of the No. 0 reduces wiring, improves the assemblability, and improves the reliability.
